Every great manufacturing company has a story. For CGCooler, that story begins not with a grand vision of global expansion, but with a simple commitment: sincere service and relentless attention to detail.
That philosophy—”treat people with sincerity, pursue excellence in every detail”—has guided the company from its founding as DONGGUAN ZHENZHI HEAT TRANSFER TECHNOLOGY CO., LTD. LIMITED in March 2018, through its evolution into the CGCooler brand in 2025, and into its current position as a trusted thermal management partner for over 25,000 customers across 15+ industries.
8 Years of Industry Experience
The numbers speak for themselves. CGCooler brings 8 years of rich industry experience to every project—experience that spans the evolution of thermal management from traditional LED cooling to the complex demands of electric vehicles, AI servers, and renewable energy systems.
This is not a company that started yesterday. It is a business that has weathered market shifts, mastered emerging technologies, and built systems that consistently deliver over 90% customer satisfaction.
Why 8 years matters to buyers:
Proven stability through multiple industry cycles
Deep understanding of long-term reliability requirements
Established supply chains and manufacturing processes
Documented track record of solving complex thermal challenges
15 National Patents: Innovation That Matters
CGCooler holds 15 national patent technologies, reflecting a sustained commitment to R&D and technical innovation. These patents span critical thermal management technologies including:
Advanced heat sink fin designs for optimal airflow
High-efficiency liquid cold plate structures
Copper-aluminum composite heat sink technologies
Heat pipe integration for passive cooling solutions
Manufacturing process innovations for quality and cost control
For customers, these patents translate directly into better thermal performance, longer product life, and more competitive pricing.

The ZZCOOLER to CGCooler Transition: A New Chapter
In 2025, the company officially rebranded from ZZCOOLER to CGCooler to better reflect its expanded global vision and comprehensive thermal management capabilities.
This was not a change of identity—it was an evolution. The same team, the same commitment to quality, the same 8 years of experience, and the same 25,000+ satisfied customers—now with a brand that speaks to a global future.
The Chinese name, 东莞市真致热传科技有限公司 (DONGGUAN ZHENZHI HEAT TRANSFER TECHNOLOGY CO., LTD.) , continues to represent the company’s domestic operations, while CGCooler serves as the international face of the same trusted organization.
